Mobile Protos fail on mobiles

Hi there. I have a prototype which works fine on desktop but not on Chrome, Firefox or Safari. Two problems.

  1. Images render in landscape mode on phones. Have checked their constraints but may be missing something here.

  2. Buttons work on desktop but not mobile, halting progress through the app. The hover state is set to a)open overlay b)manual. The positioning is correct but the button just doesnt work on mobile.

Is this because hover is irrelevant on mobile? Oops! If so, are we able to associate varied, device dependent behaviours for objects such as buttons?

Hope you can help? Thank you.
